Chevron completed its $53 billion acquisition of Hess after all legal hurdles were cleared, including the company's vast oil fields off the coast of Guyana.

Chevron has scored a critical ruling in Paris that has given it the go-ahead for a $53 billion acquisition of Hess and access to one of the biggest oil finds of the decade. Chevron said Friday that it completed its acquisition of Hess shortly after the ruling from the International Chamber of Commerce in Paris.

In an interview with Bloomberg on Friday, Wirth said the ruling by the International Chamber of Commerce in favor of Hess and Chevron is vital to the oil industry, where deal-making is essential for success.
